I'm looking for recommendations for a decent set of bluetooth headphones. Will be used mostly on travel/commuting with a Motorola Q9 (though hope to use with better devices in the future). I prefer behind-the-head style but don't have a preference for in-ear vs. over-the-ear. I'd like them to be stereo and have music controls on them (so A2DP and AVRCP). Ability to take calls is a plus. What would you recommend? Or if you can link any reviews I'd appreciate that too. Staying under $60 is preferred, but I'd consider around $100 if they were really that much better quality. Thanks.
